Be it known that I, GEORGE jZrNnsa citizen of the United States, residing at.I

l/Vapakoneta,in the county of Auglaize and State of Ohio, have invented .certain vnew and useful Improvements in Lawn Sprink-` 1ers.;v and'j do declare the following to be a lfull, clear, andlexact description of the invention, such as will enable others skilled in. lthe artto whichitappertains to make.

and use the same. ,y

My invention relates to improveinentsin water sprinklersjsuch'` as those used torlawns, iiower beds, gardens, etc., andhas reference more particularly to sprinklers of the type in which the sprinklinghead or nozzle is tuined around a vertical axis automatically by means actuated from a water wheel. Adevice of this character is shown` by inyU. S. Patent No. 1,146,228 oLtJuly` 13, 1915. ,The object however of the present invention is to generallyimprove and simplify the construction shown :by -this patented sprinkler, one of 'the improvements being the substitution of a lwater spraying nozzle for the nozzle shown by the prior patent, which nozzle merely directs a stream of water against the water wheel instead ot a spray. Ithas been foundv that this streamv of waterl yis ,injurious to smallv plants and often washes seed outofthe ground, `whereas if the water is sprayed against the water wheel, no 'such injurious results areobtained. V Y

With the foregoing in view, the invenf .tionV resides in thenovel subject matterhereinafter described and Claimed, the descrip.

'the numeral 1 designates an appropriate base from which a hollow post rises, said The carrier 11 s provid'` d withh Afri-Nr lorries. 7

This .post in' cludes a lower section 3 threaded intothejy base 1 and provided with a water ypassage 11 which communicates with a suitable waterv supply pipe withvwhich the base `,is-'provided. The upper yend of the post section-,3

is provided with an upwardly. opening sock et 6 anda worm wheel 7 rests upon'said upper end. An upright 'sleeve y8 passes .through anopening in the ,center of the worinwheel vided with a shoulder 10 which frictionally clampsthe worinl wheelgr` against the post section S, i rotation.`

Theportion ofthe sleeve 8 iininediatelivf beingalso'provided with a worm wheel 18,. .i

at` its opposite end which meshes with a i Y worin 19 A.on the vertical shaft "16X This vertical shaft is provided with a wa-ter'wheel. 20, rotation of which causes rotation of the'.

rier 11 .around the post.

worm `17 and thereby moves the ,entirecar-f A tubularrotatable post sectionH21fisrev ce'ived lwithin thesleevefS and is provided with av suitabley retaining collar 22 within`- the socket 6, a stutlng boX-23being provided at the upper end of said sleeve to--preventi leakage of waterlaround the postsection 21. The upper end of this section car-- justed by a suitable hand wheel 28.

The lower arm of the neck 2 4 carries a rigid laterally extending supplemental noz,`

zle 29 which, is intendedl 4to spray water recting'a single streamv of water against against the water wheelg20, instead of disaid wheel. `The nozzley 29 is provided with an adjustabley valve 3() operable by means of a hand wheel or the like 3l, so that the strength of the spray may be varied.` By spraying the water against the wheel 2l, instead of directing a single stream against said wheel as 1n the prior patented device, there is no danger of flood- `ing the ground around the sprinkler, of

i lthe wheel 2O rand thereby cause movement ofthe nozzle upon a vertical axis.v

' Attention is ldirected to the fact that a suitable driving connection Isuch as a depending arm 32 on the neck 24, fitting be-v tween lugs 33 on the carrier 1l is provided between said carrier and the rotatable post sectionf2l. Thus, since the worm wheel 7 cannot rotate, rotation of the worm 17 `will cause'the carrier l1 to travel around said 'n wheel and the driving connection 32-33,

causes the post section 2l and its neck and nozzles to move in the same manner; During this movement, the carrier 11 is supported against dragging upon the `worm wheel 7 byL an appropriate hanger rod 34 which extends upwardly through said .carrier and is threaded at its lupper end into a lug 35- on a ring 36 surrounding the outer end ofthe supplemental nozzle 29.

By employing the construction shown or a substantial equivalent thereof, a device is providedl which will be extremely simple and comparatively inexpensive, yet will be greatly advantageous over similar devices heretofore used.. As excellent results may be obtained from the details disclosed, it will be understood that they are preferably followed, but within the scope of the invention as claimed, numerous minor changes may of course be made. It maybe further stated that while I prefer to use two nozzles, as above set forth, together with one or twowater wheels, it will be clear that any number; of nozzles and wheels may be used.

I claim:

l. A sprinkler comprising an upright hollow post having a water inlet and, provided with a rotatable section` at its upper end carrying a nozzle, a nonf'rotatable worm wheel carried horizontally by said post, a horizontal carrier rotatable around said post over said worm `wheel and having a driving connection with said rotatable post section, a hanger for the outer end portion of said carrier preventing dragging thereof on said worm wheel, said carrier having horizontal' and vertical bearings carrying horizontal and verticalshafts, worm gearing for driving the horizontal shaft from the vertical shaft, aworm on said horizontal shaft meshingwith said worml wheel, and a water wheel on said vertical shaft disposed in the path of the water sprayed from said nozzle. l

2.l A structure as specified in claim l having said carrier provided `with a ring at its upper end surrounding said nozzle, whereby the outer end of said carrier is supported from saidnozzle.

3. A sprinkler comprising a base provided with a lower post section having a water passage, a worm wheel resting on said post section, a sleeve passing through said worm wheel and threaded into the upper end of said post section, said sleeve having a shoulder frictionally clampingl said wheel. against said post section andhaving another shoulder abovey said first named shoulder, a carrier through which said sleeve passes, said carrier being confinedbetween said second shoulder and said worm wheel, a rotatable post section received insaid sleeve, a horizontally disposed head carried by the upper end of said rotatable post-section and having one end portion curved upwardly and inwardly, upper and lower nozzles carriedv iixed my signature.
